The FLAG peptide, FLAG tag or FLAG epitope allows highly specific pull-downs with a low background. The FLAG peptide is used in many different assays such as purification, conjugation by ELISA, flow cytometry, immunoprecipitation etc. Recombinant proteins are usually expressed with affinity tag to allow their purification, conjugation by ELISA, flow cytometry, immunoprecipitation etc. This peptide is biotinylated at the N-terminus.

JPT’s Affinity Tag Peptides
One of the major setbacks in the production of recombinant proteins is the purification of the target protein from other components expressed by the organism. Therefore, recombinant proteins are usually expressed with a short peptide tag that allows for a specified subsequent affinity purification. JPT Peptide Technologies has substantial, long-standing expertise in providing peptides in all formats, scales and modifications to the global scientific community. All our catalog peptides are provided with HPLC-MS analyses to confirm the identity and demonstrate the high quality of our peptides.
